Quasar Istanbul Mecidiyeköy, which has been implemented by the Joint Venture of Swiss investment fund Viatrans and Meydanbey and become the symbol of luxury, is located on the land of the former liquor factory, right next to the former Ali Sami Yen Stadium. Quasar Istanbul project, whose Swiss quality and excellence has been certified with “The Best Residence of the World” award at the International Property Awards, is located on an area of 23,700sqm. The complex consists of Fairmont Quasar Hotel with total 212 rooms including 25 suites and 187 standard rooms; Fairmont Residence that is called as 63 Hotel-branded Service Apartments; Quasar Residence consisting of 175 flats and home offices; Podium Office Areas and a Shopping Mall with 4 cafes and 17 stores.

Quasar Residence, which changes the city's flow in the heart of Istanbul and redefines living standards with its perfection concept, combines extraordinary living spaces with office and commercial units.

Wanders, who has designed the common areas of the Quasar project and had stepped in the interior design world with his ‘Knotted Chair’, is listed as one of the important leaders of change in Europe by Newsweek in 2003. According to Washington Post’s remark: "Marcel Wanders; the favorite star of the design world."

As Ateksis, we take part in the Quasar project with Preasideo, Bosch's highest-level of public address and voice alarm system.

In our speaker system, we have system centers located independently of one another under each block. A total number of 92 amplifiers with various volume outputs and 277 sound fields with speakers that comply with the architectural design and international standards were used.

Our zone logic for the floors in Hotel and Residence tower has been considered and designed to be separate for the house-room and separate for the hallways. A music broadcasting is also possible in the elevators, if desired.

In the system room of 3 separate centers, there are desktop public address microphones connected with building security centers. These microphones make it possible to send a live public address and emergency or evacuation messages recorded on its keypad to a desired floor and inside the rooms of each tower.

Preasideo system by Bosch, which has been integrated to the fire alarm system available in the blocks, makes it possible for safe evacuation of each block in the event of a fire by making an evacuation announcement to the affected areas. Besides, thanks to the public address microphones in the security centers, it is possible to stream a live public address or recorded evacuation public address to a specific floor or all tower floors, in the event of an emergency that will require an evacuation.

With the spare amplifiers made available in the system centers; in case of a failure in any amplifiers, the spare one is enabled automatically without causing any loss in the system, which also ensures the uninterrupted operation of the system.
